Sealed disposable pouches or packets for storing and dispensing fluid compositions are well known in the art. Examples include food product packets, such as condiment packets, and medical products packets, such as lotion or ointment packets. Many types of these conventional packets are designed to be torn or separated along a defined location on the packet. However, this action requires a relatively high degree of manual dexterity and can be difficult for children and the elderly. Also, the tearing action often results in a sudden and uncontrolled release of the packet contents. Other packets are designed to burst along a frangible seam or portion when pressure is applied to the packet. Such devices are, however, not selective and burst under sufficient pressure, regardless of whether that pressure is applied intentionally by a user, or is applied unintentionally during handling, shipping, or storage.
It is also known to use packets or pouches within other structures for various purposes. For example, U.S. Pat. No. 6,508,602 describes an applicator intended to distribute a fluid from an enclosed reservoir when pressure is applied to the applicator causing the reservoir to rupture. To prevent the reservoir from bursting prematurely, the '602 patent proposes to fold the entire applicator such that the reservoir within the applicator is also folded along an axis that isolates the rupturable portion of the reservoir. To use the applicator, a consumer must unfold the device prior to inserting their hand into the applicator to apply sufficient pressure for bursting the reservoir. This configuration requires additional folding steps and packaging considerations, such as additional restraining structure or packaging materials to ensure that the applicator remains folded prior to use. This is not a desirable situation from a manufacturing and packaging standpoint.
The art is thus continually seeking improved packet or reservoir designs that are reliable and yet easy to open and use by consumers.
Objects and advantages of the invention will be set forth below in the following description, or may be obvious from the description, or may be learned through practice of the invention.
The present invention proposes a novel packet design for storing and dispensing any manner of fluid composition. The packet is easy to manufacture, maintains structural integrity during storage, will not burst during normal handling, and is relatively simple to open and use. The packet is not limited by its intended use or type of fluid composition contained within the packet. For example, the packet may contain any manner of medical lotion, ointment, salve, or other medical fluid composition. In other embodiments, the fluid composition may be a cleaning or polishing agent. The packet according to the invention may have particular usefulness in the food service industry as a condiment packet. It should thus be appreciated that the novel packet according to the invention may have utility in any number of fields, and all such uses are within the scope and spirit of the invention.
The packet may be defined by opposed first and second material layers sealed along a perimeter seal to define a sealed cavity. Exit structure is defined through the first material layer, and may be one or more openings, such as a series of holes or slits in the material layer, or a weakened portion of the packet material created by embossing, laser scoring, mechanical scoring, other known methods for weakening a film structure. The exit structure communicates with the internal cavity of the packet in which the fluid composition is contained.
Baffle structure, or other restricting structure, may be provided in the cavity to aid in controlling the flow rate of the fluid composition out of the packet. The baffle structure may be defined by one or more seals between the opposed material layers of the packet that define a restrictive flow path for the fluid composition.
A flap is defined by a portion of the opposed packet material layers folded at a first fold line so as to extend over and releasably seal to the first material over the exit structure. In its folded and sealed configuration, the flap may be grasped directly by the user, or a flap extension may be provided having a shape and configuration to be readily grasped by the user. While holding the packet, the user simply pulls the flap, or flap extension, in a direction that causes the flap to peel away from the first material layer and unseal from over the exit structure. The fluid composition is then delivered out of the packet through the exit structure upon pressure being applied to the packet by the user.
In a particular embodiment, a seal line between the opposed material layers of the packet may be provided between the flap and the cavity, with the flap folded over at this seal line so as to extend over the exit structure and seal to the first material layer in a first pass. The flap may then be folded back in an opposite direction at a second fold line so as to extend back over the exit structure in a second pass. Although not necessary for seal integrity of the flap over the exit structure, the flap may be releasably sealed to the second material layer adjacent the second fold line so that the flap is held in a compact and tight configuration against the packet prior to use.
The packet material layers can vary. In certain embodiments, laminated metallized films may be desired depending on the nature of the fluid composition within the packet. In a particular embodiment, the opposed material layers of the packet include heat sealable thermoplastic materials, such as thermoplastic film layers, heat-sealed together along a perimeter seal using conventional heat seal techniques. The flap may be heat sealed directly to the first material layer in a seal zone that circumscribes the exit structure. The seal zone may be a border around the exit structure, or a continuous seal zone that encompasses the exit structure. In this embodiment, the first material layer may have an outer surface or layer with heat seal characteristics different from those of an inner surface of the material. In this way, the flap may be heat-sealed against the first material layer at heat seal conditions (i.e., temperature, dwell time, and pressure) different from those needed to heat seal the opposed material layers together along the perimeter seal. The flap seal may thus be considered weaker or “frangible” as compared to the perm perimeter seal defining the cavity, or other pouch structure. The first material layer may be, for example, a multi-layered film with different layers having different melt points. The layers may be co-extruded or laminated layers, with one of the outer surface layers including a sealant material or coating, such as Surlyn® from Dupont, or a blend of polybutylene with ethylene vinyl acetate or ultra low density ethylene copolymers, polyolefin plastomers, or polyethylene. Sealant layers made with these resins or blends may provide seals of varying seal strength as compared to the base polymer depending upon seal temperature, dwell time, and pressure. Thus, the seal between the flap and outer surface of the first material layer can be made selectively frangible as compared to the permanent perimeter seal defining the packet cavity by varying the sealing conditions.
The second material layer may be the same or a different thermoplastic film as compared to the first material layer.
In still another embodiment, the flap is folded at a second fold line disposed such that the exit structure (with sealed flap) is folded in a direction so as to lie adjacent to the second material layer. In this configuration, the exit structure is isolated from the contents of the cavity by the second fold line. The flap is releasably sealed to the second material layer adjacent to the second fold line. In this embodiment, the opposed material layers may be thermoplastic materials heat-sealed together along a perimeter seal defining the cavity. The flap is heat sealed directly to the first material layer over the exit structure in a seal zone that circumscribes the exit structure, and is heat-sealed directly to the second material layer adjacent the second fold line. The first and second material layers may be multi-layer films having an outer sealant layer as discussed above with heat seal characteristics such that the flap is heat sealed against the first and second material layers in a frangible releasable seal as compared to the perimeter seal defining the cavity.
With yet another embodiment, the packet may be defined by a combination of opposed material layers heat sealed together along a perimeter seal defining the cavity, with the flap heat sealed directly to the first material layer over the exit structure in a seal zone that circumscribes the exit structure. The flap seal is formed at a temperature, dwell time, and pressure so as to be frangible as compared to the perimeter seal. In order to prevent the opposed layers from sealing to each other in the flap seal zone when heat sealing the flap to the first material layer, an insert device may be disposed within the cavity at a location relative to the seal zone to prevent the material layers from sealing together within the cavity. The insert may be any material that will not seal to both of the opposed material layers upon heat-sealing the flap to the first material layer. In a particular embodiment, the insert may be a strip of thermoplastic material having at least one surface that will not heat seal to the opposed material layers. The opposite surface may have a sealant layer so that the insert material seals to the bottom material layer within the cavity. The insert thus defines a channel or conduit to ensure that the fluid composition is free to flow out of the exit structure upon the flap being peeled away from the first material layer.
Aspects of the invention will be described in greater detail below by reference to particular embodiments illustrated in the figures.
Reference will now be made in detail to one or more embodiments of the invention, examples of which are illustrated in the drawings. The embodiments are provided by way of explanation of the invention, and are not meant as a limitation of the invention. Features illustrated or described as part of one embodiment may be used with another embodiment to yield still a different embodiment. It is thus intended that the present invention include modifications and variations to the embodiments illustrated and described herein.
It should be appreciated that the novel packet according to the invention is not limited to any particular intended use or type of fluid composition stored in the packet.
Referring to the figures in general, various embodiments of a packet 10 are illustrated. In the embodiment of
As seen in the various figures, the packet 10 defines a cavity 12 in a first portion of the packet, with the fluid composition 14 contained within the cavity 12. The packet 10 may be formed from opposed material layers 16, 18 attached together to define the sealed cavity 12. The opposed layers 16, 18 may attached by thermal bonding, although any suitable attachment method may be used depending on the type of material selected for the layers 16, 18.
The packet material layers 16, 18 may be made from any suitable flexible material that is impermeable to the fluid composition 14 contained in the cavity 12. The packet materials should have no negative impact on or reaction with the fluid 14. The materials used in the construction of the packet 10 and the fill level of the fluid composition 14 within the cavity 12 create a structure that is durable and flexible, and one that is not easily burst open during normal handling. The packet 10 may be formed from the material layers 16, 18 using any conventional attaching techniques, such as adhesives, stitching, welding, heat-sealing, ultrasonic, and so forth. In particular embodiments, the material layers 16, 18 are a heat sealable thermoplastic material, such as a polyethylene or polypropylene film, or other suitable thermoplastics. The layers may also be metallized films. It should be appreciated that the bonding or attaching techniques used to form the packet 10 and associated structure will be a function of the type of materials selected for layers 16, 18.
The packet 10 may include one or more bond points or seals between the opposed layers to define the cavity 12, or other features of the packet. For example, referring to
Exit structure 28 is provided in a first of the packet material layers, such as layer 16, through which the fluid composition 14 flows in use of the packet 10. Configuration of the exit structure 28 can vary. For example, the structure 28 may comprise any pattern of holes, slits, apertures, or other openings defined completely through the material layer 16. In alternate embodiments, the exit structure 40 may be weakened positions in the packet material or seam structure designed to rupture or burst upon pressure being exerted on the packet. Such weakened positions may be created by embossing, laser scoring, mechanical scoring, or other known methods for weakening a film structure.
The packet 10 incorporates a flap 30 that is formed from an extension of the opposed packet material layers 16, 18 that may be sealed together in a second portion of the packet 10 that is adjacent to the first portion defining the cavity 12, as particularly illustrated in
In particular embodiments of the packet 10, the opposed material layers 16, 18 are thermoplastic materials, such as thermoplastic film layers, heat sealed together along the perimeter seal 20 to define cavity 12, and also baffles 22 and nozzle structure 26 if desired. With thermoplastic materials, the flap 30 may be heat sealed directly to the first material layer 16 over the exit structure 28 in a seal zone 27 (indicated by the dashed lines in
The material layer 16 may be a multi-layered film with different layers having different heat seal characteristics. The layers may be co-extruded or laminated layers, with one of the outer surface layers including a sealant material or coating, such as SURLYN from Dupont, or a blend of polybutylene with ethylene vinyl acetate or ultra low density ethylene copolymers, polyolefin plastomers, or polyethylene. Sealant layers made with these resins or blends provide different seal strengths depending upon seal temperature, dwell time, and pressure as compared to the base polymer material. Thus, the seal between the flap 30 and outer surface of the first material layer 16 can be made selectively frangible as compared to the permanent perimeter seal defining the cavity 12 by varying the sealing conditions. The flap 30 can be heat sealed directly to the material layer 16 over the exit structure 28 without concern of the inner surfaces of the material layers 16, 18 being sealed together within the seal zone 27.
The second material layer 18 may be the same or a different thermoplastic film as compared to the first material layer 16, so long as a seal can be formed with the inner surface of the material layer 16.
Various multilayer thermoplastic films are commercially available and may be used to form packets 30 as described herein. For example, a line of multilayer thermoplastic films under the name PERFECFLEX® films are available from Perfecseal, Inc. (a division of Bemis Company, Inc.) having a principal place of business in Oshkosh, Wisc., USA. A particularly suitable film from Perfecseal, Inc., is identified as EZ PEEL® Polyethylene Film (product code 34466-G). This film is a multilayered PE film having a frangible sealant layer on one outer side of a core layer. For use as material layer 16, this film is oriented so that the frangible sealant layer is outwardly facing and, thus, defines the mating surfaces of the flap 30 and material surface 16 when heat sealing the flap 30 directly to the material 16. The EZ PEEL® film (without corona treatment on the opposite outer side) may also be used as the opposite material layer 18, with the frangible sealant layer of the film outwardly disposed.
The flap 30 may be grasped directly the user to open the packet 10. In alternate embodiments, the flap 30 may include a longitudinally extending tab or extension 32 that presents an element to be grasped by the user to open the packet 10. The extension 32 may take on any desired shape or configuration. When the extension 32 is pulled, the flap 30 is caused to unfold and release from the material layer 16, and thereby uncover the exit structure 28. The fluid composition 14 within the cavity 12 is then free to migrate out of the exit structure 28 in the embodiment wherein the exit structure 28 includes holes or other openings through the packet material. In the embodiment wherein the exit structure 28 includes weakened material portions, the packet is activated by the user applying pressure to the packet (for example, by squeezing the packet) causing the weakened material portions to burst.
It should be appreciated that the seals 38 and 40 may be provided by an adhesive composition disposed between the mating surfaces, particularly in embodiments wherein non-thermoplastic materials are used as packet layers 16, 18, or bonding techniques other than heat sealing are used to construct the packets 10.
It should be appreciated that any embodiment of a packet 10 according to the invention may be made from various combinations of single and multi-layer films selected to have desired heat seal characteristics for defining the perimeter seal of the cavity 12, as well as any baffle seals 22 or nozzle seal 24, and the flap seal 38 (and seal 40 if included). With certain combinations of films, care must be taken to prevent the material layers 16, 18 from sealing together and collapsing the cavity 12 at the exit structure 28 when forming the seal 38. In this regard,
In the embodiment of
The fluid composition 14 contained within the packet 30 may be any fluid suitable for the intended use of the applicator 10, including cleansing fluids for human/animal use and cleaning fluids for cleaning surfaces. The fluid may be any paste, gel, powder, oil, liquid, or any other appropriate medium. Example cleansing fluids include surfactants such as water-soluble polymers, polysorbates, glycerins, glycol-based surfactants, and/or silicone-based surfactants. The fluid may include other materials, such as water, salts, vinegars, humectants, scouring powders, thickening agents, and fragrances. A cleansing fluid may also include a moisturizer that helps to maintain a normal skin hydration level. A cleansing fluid may also include preservatives and other ingredients that do not disrupt the normal flora of the vaginal area (e.g., sorbic acid, citric acid, methyl paraben, and natural preservatives such as grapefruit extract). The fluid may include other materials that may be applied to an area of the body. Example materials include lubricants, deodorants, and other inactive or active ingredients (e.g., spermicidal agent or medication). In one aspect of the present invention, the fluid is a cleansing fluid that is primarily a water-based solution (90%+water content) with a surfactant, preservatives, pH neutralizers, and a thickening agent.
The fluid may be a cleaning solution such as FOUR PAWS Super Strength Stain and Odor Remover, which includes water, natural enzymes, and mild detergent (from Four Paws Products, Ltd., Hauppauge, N.Y.), or NATURE'S MIRACLE Stain & Odor Remover, which includes water, natural enzymes, isopropyl alcohol, and natural citrus scent (from Pets 'N People, Inc., Rolling Hills Estates, Calif.), or RESOLVE Carpet Spot & Stain Carpet Cleaner (from Reckitt Benckiser, Wayne, N.J.). The fluid may be a pet shampoo. The fluid may be a stain cleaner and stain guard such as SCOTCHGARD Oxy Carpet Cleaner with Stain Protector that includes water, 2-butoxyethanol, hydrogen peroxide, and surfactants (from 3M Corporation, St. Paul, Minn.). In the case of using the cleaning device 10 to clean a fabric surface, the fluid may include a pet repellant such as SIMPLE SOLUTION Indoor/Outdoor Repellent for Dogs and Cats, which has as an active ingredient methyl nonyl ketone (from The Bramton Company, Dallas, Tex.).
The fluid may be an antimicrobial. Examples of suitable antimicrobials include quaternary ammonium compounds such as 3-trimethoxysilylpropyldimethyloctadecyl ammonium chloride (AEGIS); poly cationic chemicals such as biguanides(poly(hexamethylene)biguanide hydrochloride (PHMB) Arch Chemical), 2,4,4′-Trichloro-2′-hydroxyl-dipenylether (Tinosan, Ciba); diphenyl ether (bis-phenyl) derivatives known as either 2,4,4′-trichloro-2′ hydroxy dipenyl ether or 5-chloro-2-(2,4-dichlorophenoxyl)phenol; triclosan; silver; and copper. The fluid may be an allergen sequestrate that may be a charged or mixed charged particle or nanoparticle. Most allergy proteins are glycoproteins (proteins that contain covalently-bound oligosaccharides), so a negative charge may be better then predominance of positive charges on the particles, although mixed charges may be preferred. Clays or modified clays work in this respect. Examples of suitable allergen sequestrates include plant lectins with an affinity for N-acetylgalactosamine such as jacalin, peanut, and soybean, where the lectins both bind allergens and are bound to the web, thus removing allergens from a surface. The fluid may also include a fragrance. The fluid may also include a pheromone to either attract or repel an animal. The fluid may also be shoe polish, a carpet cleaning solution, a stain removal fluid, kitchen floor and counter top cleaners, etc.
Embodiments of the invention have been described with reference to various specific and illustrative aspects and techniques. However, it should be understood that many variations and modifications may be made while remaining within the spirit and scope. Accordingly, this is intended to embrace all such alternatives, modifications and variations that fall within the spirit and scope of the appended claims.
